I recently purchased this processor due to an upgrade from a AMD 64 X2 4600+ 65W that I had originally. When I installed this new CPU into my Abit AN9 32X motherboard it booted up perfectly fine and has been working since. But, I have ran into many problems that are very frustrating.

First off, the processor is overheating like mad. What I am talking about is an idle of 45C or higher in the BIOS and a full (Dual Core) Orthos Stress Test load of 75C. This is even on a Sunbeam Core Contact Freezer I updated towards as well. I even took the original fan it came with off for a Silverstone FM121 fan that I had laying around. It's spitting out 133 CFM at the heat sink and it should be ice cold and yet it still over heats to + 70C.

The settings at which I have my motherboard are:
Multiplier: 15.5X
Front Side Bus: 200
Vcore: 1.45
and everything else is at default

I am baffled as to why the CPU is acting like a space heater at these temperatures and hope that someone can help me solve this problem as their help would be much appreciated. If further information is required, I will be happy to oblige to your requests.

Further note, When I play games and it loads to about more than 50% load on the CPU, I had a game running in the back ground and the CPU temp in everest was at 70C constant. When it at full blown 100% load the processor cooks to a scorching + 80C.

I am going to run Everest as you have stated and I will provide a huge array of photography of not only my case, but BIOS screens, and various temps on different programs.

EDIT: I have noticed something very intesresting. If I use hardware monitor from CPU-ID; With max speed on all my fans on I get a idle of 30C which makes sense. Then, when I run Orthos stress prime it jumps to 45 C and then readd back to 35C and skyrockets to 65C and eventually fails.

I also began to read about Brisbane cores has a thermal diode problem of incorrectly reading the temperatures. If so, could I have one of these defective CPU's and how can I tell the true temperature my CPU is "cooking at".

I read over the bottom of your post and immediately said "I bet he has an Abit AN9 32X". Then I read the top of your post and realized that you do have an AN9 32X.

I have the exact same problem and the exact same motherboard. The problem is the core voltage and I am surprised that noone in this forum has mentioned that yet. I believe the core operating voltages for this CPU is 1.1V to 1.3V. The motherboard we have unfortunately dials down only to 1.4 which is well over the operating voltage.

I can play games, etc. without any issues however I can not run and test/stress tools on my system as it reaches max temp in two seconds and reboots. I was hoping that Abit would release a new BIOS to allow lower core voltages however considering that they are out of the motherboard business here in the US this is an unlikely scenario.

If there is a hack of any kind out there (a hacked BIOS dump, etc.) or any other kind of utility that we can use, I would greatly appreciate it if someone let us know.

That is odd, I had checked the AMD specifications on this CPU before and it had said 1.1 to 1.3 for core voltage and checked immediately after my previous post adn now it says 1.1 to 1.4. Anyway, now the reported voltage of 1.425 does not look as bad.

Howevever, using uGuru I am seeing that the CPU voltage on my machine is reported as 1.5 which is still a problem. I think I will wait a couple of weeks for new BIOS and then get a new motherboard and see what happens.

I have fixed the temperature problems so far. I had to reseat my CPU cooler and use a different method of apply thermal paste to a DHT cooler. My temps at maximum are now 50C. Although, if I run ORTHOS with both cores at 100%, it can only go for 30 minutes maximum without overheating again. BUT, it is stable now and I have fixed the problem. Now I wish a BIOS update would kick in for this specific motherboard to fix the vcore voltage issue.

Finally. It had nothing to do with reseating the CPU. The root cause of the issue was explicit however I had refused to see it as it meant purchasing a new motherboard.

As I completely lost confidence in Abit releasing another BIOS update for the AN9 32X, I went and purchased another motherboard (ASUS). This thing now idles at 33C and never reaches above 55C. I can not believe the difference a "true" quality motherboard made. For all AN9 32X owners, sad to say but a new motherboard is your only option.

What is funny is I have noticed a lot of people having problems with this processer via overheating.
I have the same processer and yes I had the high heat issue also.
I used to idle at 49-51c,under load it goes to 65c.

I used RMclock to lower my voltages as the Asus M2N68-AM board does not support lowering voltages.
I set my voltage to 1.32 and I run 42c idle and 48c under full load.

This 3.1 89w Brisbane is the pickiest Proc I have ever seen,with my current computer set-up the thing should run like a ice cube.

I also have a Intel P4 3.0 Extreme with the stock cooler and it doesn't run as hot as the AMD.

But my main point I have learned is do some research on mobos,if you can't actually lower the voltage in BIOS then look for another motherboard,next time I will.

Well ive tried some undervolting today with much better temp results !

I tried 1.1volts and got Bsods at bootup, so went too 1.2volts and got the samething with bluescreens.

I have tried 1.25 volts and ran orthos for about 30 minutes but sadly orthos gave me a red screen error saying hardware failure and it stopped. CPUZ still oddly reports my Vcore @ 1.275-1.3volts ? But the Temps were excellent I maxxed out around 60-65c which id be happy with but since orthos failed gotta keep re-trying I guess.

I am now re-trying 1.275 volts, CPuz still says 1.325volts+ seems too change a tad back and forth and retrying Orthos again Im hoping too keep it under 70c Since orthos isnt a normal day to day activity for PCing I doubt the owner of this pc will stress it that much ever !
